Notes. aI5103 = IRAS 15013−5754, I15445 = IRAS 15445−5449, I18019 = IRAS 18019−2219, I18443 = IRAS 18443−0231, I18464 = IRAS 18464−0140, and I18480 = IRAS 18480+0008. bBroadband K magnitudes were taken from 2MASS, except for that of IRAS 18019−2216, which was taken from UKIDSS. cCoordinates of the radio continuum emission reported in Suárez et al. (2015) and Cala et al. (2022, 2025). dDetector integration time eNumber of frames. fTotal integration time.
